Definitions

  • the present invention relates to portable terminals, such as cellular phones, Personal Digital Assistants, hand held phones, game phones and camera phones. More particularly, the present invention relates to a hinge device for rotatably coupling a pair of housings of a portable terminal to each other.
  • a portable terminal is a device for providing a wireless communication function between users, or between a user and a service provider through a mobile communication base station.
  • a user can receive and use through the portable terminal various kinds of services, such as a voice communication service, a short message sending service, a mobile banking service and a TV viewing service, and contents such as on-line games, video-on demand, and the like.
  • the portable terminals can be generally classified, based on their shapes, into bar type portable terminals, flip-type portable terminals, folding type portable terminals, and sliding type portable terminals.
  • Bar type portable terminals have a communication circuit and an input/output device such as a transmitter and a receiver disposed in a housing, and a flip type portable terminal has a flip cover which is coupled to a bar type portable terminal.
  • a folder type portable terminal has a pair of housings which are capable of rotating and opening and have an input/output device which is arranged on the housings.
  • the sliding type portable terminal has been recently developed and increases the portability and convenience of a portable terminal.
  • the sliding type and folder type portable terminals have been favored by individual users.
  • a portable terminal with a camera lens assembly not only takes pictures, but has also contributed to the commercialization of image communications.
  • the conventional hinge device imposes limitations on the design and specification of the portable terminal. That is, although the portable terminal may have various widths from about 30 mm to above 50 mm, the portable terminal must have a pair of rotatable housings constructed by using the hinge device having a length larger than 10 mm. Therefore, it is difficult to change the design and the specification of the conventional portable terminal and to secure a space for mounting parts in the conventional portable terminal.
  • Another aspect of the present invention is to provide a hinge device for a portable terminal which can allow changes in the design and specification of the portable terminal and enable the portable terminal to provide a space in which parts are mounted.
  • a hinge device for a portable terminal having a first housing and a second housing rotatably coupled to the first housing rotatably couples the first housing to the second housing of the portable terminal.
  • the hinge device comprises a first hinge cam fixed to one of the first and second housings of the portable terminal and having a cam groove on a surface of the first hinge cam, a second hinge cam fixed to the other of the first and second housings of the portable terminal and rotatably received in the cam groove, so as to make friction with an inner wall of the cam groove.
  • a portable terminal comprises a first and a second housing, a first hinge cam disposed on the first housing, the first hinge cam having a cam groove with an inner wall, and a second hinge cam disposed on the second housing.
  • the second hinge cam comprises a pair of cam members, and at least one elastic member disposed between the pair of cam members, the elastic member biasing the cam members towards the inner wall of the cam groove.
  • the first hinge cam 101 has a cam groove 111 formed on a surface thereof, and a supporting shaft 113 extending along a hinge axis A from a bottom surface of the cam groove 111.
  • the second hinge cam 102 is received in the cam groove 111 to enclose the supporting shaft 113.
  • At least one stopper groove 112 is formed on an inner surface of the cam groove 111.
  • a pair of stopper grooves 112 is formed with equal angles along a circumference of the cam groove 111.
  • the second hinge cam 102 is rotatably received in the cam groove 111 so as to generate friction with respect to the inner surface of the cam groove 111.
  • the second hinge cam 102 includes a pair of cam members 121, and elastic members 129 extending between the cam members 121 to provide elastic force in a direction that the cam members 121 are spaced apart from each other.
  • the elastic force of the elastic member acts so that the cam members 121 come into contact with the inner wall of the cam groove 111.
  • the cam members 121 respectively have a stopper protuberance 123 formed on the outer peripheral surface thereof and a guide groove 125 formed on the inner peripheral surface thereof.
  • the guide grooves 125 and the guide protuberances 137 are able to restrain the second hinge cam 102 from rotating with relation to the hinge cover 103, preferably with respect to the housing to which the second hinge cam is coupled, while having to maintain a condition under which the cam members 121 move straight.
  • FIGS. 5 to 7 show a portable terminal 200 having the hinge device 100.
  • the portable terminal 200 as shown in FIGS. 5 to 7 includes a first housing 201, a second housing 202 rotatably assembled with the first housing 202, and a third housing 203 slidably moving on the second housing 202.
  • the third housing 203 slidably moves and opens a part of the second housing 202 while closing a part of the first housing 201.
  • the first housing 201 is provided with a keypad 211 and a receiver 213 which are installed on a surface of the first housing 201. Accordingly, as the second housing 202 rotates, the keypad 211 and the receiver 213 are opened and closed.
  • the first housing 201 has first side hinge arms 215 formed at both sides of an upper end portion on a surface thereof.
  • the first side hinge arms 215 have covers 217 attached to an outer surface of each first side hinge arm 215, respectively.
  • the covers 217 are used for decoration in the portable terminal 200. Furthermore, the covers 217 may be replaced with speaker units.
  • the second housing 202 includes a sub-display unit 221, a camera lens 227, and a flash unit 228 which are installed on an exterior surface thereof, while having an auxiliary keypad 223 mounted on an interior surface thereof, and open and closed by means of the third housing 203.
  • the second housing 202 has second side hinge arms 225 formed at both sides of one end thereof, so that the second side hinge arms 225 face the first side hinge arms 215.
  • the hinge device 100 is disposed between the inner surface of the first side hinge arm 215 and the outer surface of the second side hinge arm 225. At this time, the hinge device 100 is interposed between two pairs of first and second side hinge arms 225, or only between a pair of first and second hinge arms 225.
  • the third housing 203 is provided so as to slidably move on the second housing 202, as described above, on which a main display unit 231 and the receiver 233 are mounted.
  • the portable terminal 200 is suitable for voice communication, like the general folder type portable terminal.
  • the third housing 203 is restrained from slidably moving. That is, the third housing 203 may slidably move only when the second housing 202 is unfolded by an angle of about 180 degrees from the first housing 201.
  • the first hinge cam 101 of the hinge device 100 is coupled to one of the first and second housings 201 and 202, while the second hinge cam 102 is assembled with the other of the housings.
  • the hinge cover 103 is first fixed to the inner surface of the first side hinge arm 215, which in turn the second hinge cam 102 is assembled with the hinge cover 103 and received in the cam groove 111 of the first hinge cam 101.
  • the first housing can be rotatably assembled with the second housing 202 by means of the hinge device 100.
  • the main display unit occupies almost all of the second housing in the conventional folder type portable terminal. Further, it is impossible to assemble a separate housing having the display unit with the second housing so that the separate housing slidably moves on the second housing. This is because the conventional hinge device installed in the separate housing acts as an obstacle due to its length during the sliding movement of the separate housing on the second housing.
  • the hinge device 100 has a reduced length because the second hinge cam 102 is received in the cam groove 111 of the first hinge cam 101. Therefore, it is possible to install a separate third housing 203 capable of sliding on the second housing 202 while maintaining the shape of a typical folder-type portable terminal.
  • the hinge device for the portable terminal has a reduced length and can occupy significantly reduced space in the portable terminal. Further, the hinge device allows the separate housing to be installed to the portable terminal while maintaining the shape of the portable terminal so that the separate housing slidably moves, thereby contributing to the variety of possible designs for the portable terminal. Furthermore, since the hinge device requires a small space in the portable terminal, the specifications of the portable terminal may be easily changed.
